Magnetic Tri Mini Fidget Spinner for smaller hands

thingiverse

I created a spinner that was too big for a 7-year-old's hands, so I decided to build one using N42 cylindrical neodymium magnets and smaller R4Z bearings on hand. I included a picture of these bearings compared to the more common 608z, but this project definitely doesn't work with 608z bearings! Be careful when working with magnets - use caution!
